AI Technical Summary

Benefits of technology

[0006]From the foregoing, it is apparent there is still a great and long-felt need for a rotary apparatus, in particular a rotary head assembly, that provides quick and easy insertion of a cutting member in order to resume operation as well as simple and efficient removal of the cutting member when replacing it. The present invention addresses the foregoing need, amongst other needs, in a highly unique and facile way. Thus, in one aspect, the present invention provides a novel rotary apparatus, particularly a rotary head assembly from which a cutting member may extend. Particularly, in at least one of its aspects, this invention provides quick and easy insertion of a cutting member in order to resume operation of the rotary apparatus. In another aspect, the invention also facilitates removal of a cutting member during change out, so that there is no need to disassemble the rotary head assembly of the rotary apparatus, as required in other known trimmer apparatuses. The cutting member of the present invention can be flexible (e.g. wires, strands, etc.), semi-rigid (e.g. plastic blades), or rigid (e.g. metal blades) and may be made of any material and in any shape capable of cutting unwanted plants such as weeds. Non-limiting examples of cutting member materials include plastics (e.g. nylon), metals, metal alloys, and combinations thereof.

Problems solved by technology

However, such weed trimming apparatuses have certain drawbacks which have gone largely unaddressed in this technical field.

Stress on these apparatuses' trimming lines will cause it break from time to time during use.

Because of their designs, the trimmer lines often get twisted, tangled or buried within the spool making it difficult to dispense the proper line length for cutting.

This process is difficult, labor intensive and highly time consuming.

As the blades become dull or the trimmer lines break, often times, it require additional tools and / or a lot of time to replace the worn or broken pieces.
